Claims.

This invention relates to apparatus for the these and other advantages,which will be of sim-- unloading or dumping of cars, and While it willhereinafter be described as embodied in an apparatus particularlydesigned for the dumping of cars carrying a finely divided or'pulverantmaterial, such as starch which has been dried in a kiln, it will readilybe understood that the entire invention and its several features arecapable of other valuable embodiments and uses.

Prior to my invention it has been known to load finely divided material,such as starch, in

moist condition into cars having cellular bodies. I'he cars so loadedhave been run through kiln tunnels in which a warmed drying medium iscaused to circulate through and around the cells to accomplish drying.After being removed from the kiln tunnels, the cars loaded with thedried pulverant material have been run upon the platform of a tipple ordumper, where they have been locked in place and the platform with itsloaded car revolved by power to an inverted position to accomplishdischarge.

An important object of the invention is the provision of a dumpingapparatus for a car 25, which will move from a car receiving to adumping position and back again thereafter to normal position withoutthe use of power, and through inverting and return movements induced andaccomplished by the shifting of the center of gravity of the entire massas a result of the discharge of the contents. A car for drying starchand the like comprises arelatively light body built up of screenscarried in a framework, and a chassis of relatively heavier and'sturdierconstruction. My invention has for an important object the provision ofa'tipple or dumping apparatus which will engage and suspend the car fromthe relatively stronger chassis during the entire discharging operation.

Another important ob-jectof the invention is the provision for vibrationof the car to insure complete discharge of the contents. The inventioncontemplates in this regard, mechanism and devices which act upon thechassis or running 3 gear of the car as contradistinguishedfrom the bodyto accomplish the vibration, the body being preferably left free forvibratory movement.

Another important object of the invention is the provision of a cardumping apparatus which will effectively and in minimum time dischargepulverant material having'tendency to adhere to the cells of the body,and this with a minimum of labor.

Another important object of the invention is 5 the provision of adumping apparatus having ple construction, and devoid of parts likely torequire frequent repair, replacement, or readjustment.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, takenin connection with the accompanying drawings, discloses a preferredembodiment thereof.

Fig. 12 is an enlarged fragmentary, horizontal section of the same; and

Fig. 13 is a fragmentary side elevation of the portion of control.

Referring first more particularly to Fig. 1, ref erence character 21indicates a pit in which hoppers 22' are located for the reception ofthe discharged material. These hoppers empty into anair disposal system23, discharge of the material from the hoppers into this system beingcontrolled by valve mechanisms 24. The dumping mechanism to be presentlydescribed in detail and embodying the present invention is located abovethe pit, and receives loaded cars from rails 2'7, which lead from thedrying kilns. After dumping, each car generally indicated at 26, ismoved off the dumping apparatus onto tracks'25, which lead to or maylead to transfer tracks or cars (not shown) which return them back toreceive a new charge of material to be dried. The details of the partsjust described are not thought necessary to an understanding of thepresent inindependent rotation by keys 41.

vention and description of them is accordingly not undertaken.

Car 26, as shown on the drawings, is one particularly adapted for use inthe drying of starch, which consists generally of a chassis 1 of heavystructural steel construction, and a superstructure or body 2 ofrelatively light and frail material. The chassis is supported upon axles3 and wheels 4 which engage the rails 2'1. The body is, of course,relatively much larger than the chassis and is or may be constructedmerely of horizontal and vertical frame members 5 and 6, braced bydiagonal bars '7, with foraminous side walls 8.

The dumping apparatus comprises generally side supports 28 and 29, fromwhich is suspended a car receiving platform, generally indicated at 31.extend up from each side of the platform (as may be seen in Fig. 4).Each of these truss structures comprises, in the present instance, twocentrally arranged vertical members 32 connected together by crossplates 33, 34 and 35, and cornprises also angularly arranged end braces36. Each truss structure is suitably connected with the platform in anyusual or preferred manner.

The platform itself is likewise built up of relatively heavy and wellbalanced structural iron. The side truss structures and the platformconstitute a single rigid and sturdy construction. The central plates 34are provided with oppositely extending bosses 39 through which aremounted flxed shafts constituting the bearing trunnions 38, these shaftsor trunnions being held against The trunnions or shafts 38 are arrangedfor rotation through bearings 42 at the tops of the side supports 28 and29.

One of the trunnlons 38, i. e. the trunnion at the left viewing Figs. 8and 9, is provided with two brake drums 43 and 44, each of which isembraced by a brake band 4546, the brake drums being connected to thetrunnions by a key 40. A shaft 4'7 is arrangedbeneath the brake drumsand is mounted through bearing plates 50 forming parts of the sidesupport 29. This shaft is directly beneath and is arranged parallel tothe axis of the trunnion 38. The brake bands 45-46 are secured to thisshaft by anchoring members 45 and 46 and extend from this shaftoppositely around the drums. The other ends of the bands are providedwith rods or bolts 48 and 49 respectively, which are arranged througharms 51 and 52 pivoted upon the shaft 47, these arms being bifurcatedwhere they engage the shaft to permit arrangement of the anchoringmembers 45 and 46 between the separated end portions of the arms, as maybe seen in Fig. 12.

The arms 51 and 52 extend downwardly and their lower ends are separatedto receive brake release cams 59 and 60 mounted upon a rock shaft 61arranged beneath the shaft 47 in bearing members 50 of the side support29. a I

A rod 53, having an enlarged head 54, is arranged to extend through thearm 52 and through the more remote side of the side support 29. The

outer end of the rod 53 is threaded at 55 and is embraced by a spring 56which presses against the presented face of the side support 29 andagainst a washer 5'7 held on the rod by nuts 58 The spring engaging saidthreaded portion 55. 56 pulls the brake band 46 into braking positionand against the release cam 59 already described.-

A similar rod 63 is similarly arranged through the arm 51 and isprovided with a spring 64 simi- A fabricated truss structure is arrangedto larly mounted upon its end beyond the side support 29. The rod 53normally urges the brake band 45 into braking engagement with its drumand against the release cam 60, already described.

A brake releasing pedal 65 is secured at 65 upon a rock shaft 61 and isadapted, when depressed, to release both brakes at the same time.Rocking of the rock shaft separates the arms 51 and 52, compressing thesprings 56 and 64 to release the brakes. The two band brakes justdescribed are oppositely acting and control or stop the movement of thecar carrying platform in its two directions.

The platform normally assumes approximately the position shown on thedrawings, i. e. car receiving position, since it will be noted that thecenter of gravity of the platform in this position is much below theaxis of rotation, i. e. the axis of the trunnions 38. The constructionand arrangement of the parts is such that the center of gravity of thecombined mass of the platform and of an empty car is below this axis.When, however, a loaded car is placed upon the platform, the load in thecar shifts the center of gravity of the combined mass to a locationabove the axis of the trunnion 38, and the tendency is for the platformwith this car to rotate to an inverted position without the employmentof power or manual impulse.

Two rails 67 are arranged upon the platform for registration with therails 25 and 27 already described, and side channels 68 (Fig. 9) aremounted upon the platform with their flanges extending inwardly towardits longitudinal center. An angle iron 69 is arranged upon the upperhorizontal flange of each channel iron 68 and with the associatedchannel flange '71 forms a support for the car when the platform isinverted. Reference character '70 indicates a main side channel memberof the car chassis. 72 is secured along each chassis channel member '70in position to receive the channel flange '71 and the angle member 69between its flanges.

Means, which will now be described, are provided to lock the car to theplatform, when, and onlywhen, it has arrived at the desiredpredetermined position upon the platform. The primary locking elementsof this means consist of four pins '73 (Fig. 9) arranged throughbearings 74 carried in the angle irons 69 and located one near each endof each side of the car position. These pins are adapted to enter intofour appropriately arranged vertically elongated openings '15 in thechannels 72 and when these openings are presented for their reception.Each pin 73 is connected by a pin and slot connection 76 to the upperend of an arm '77 which is fixed upon a rock shaft '78 extendinglongitudinally of and carried beneath the platform in bearings 79. Ashaft '78 is arranged at each side of the platform, and two arms withtheir associated pins extend up from each shaft.

A lever having two arms 81 and 82 is fixed upon each shaft '78 beneaththe axis of the trunnion. The arms 81 of the two levers meet at thecenter of the platform where they are connected by pin and slotconnections 83 to a yoke 84, above which is mounted a spring 85 arrangedin a spring barrel 86, so that the spring normally presses down upon thearms 81 of the levers to thrust the pins '73 into interlocking relationwith the car.

A control, to be presently described, normally maintains the pins 73 inretracted position. When the pins are in this position the outer arms Acar supporting channel.

82 of the two leversarear'ranged inslots provided in angle irons 90secured in the pit in appropriate position. Since the axis of rotationis located at the centers of the trunnions 38, disposal of the arms 82of the levers in the slots 80 looks the platform against rotarymovement.

The control for holding the pins '73 in retracted position and the leverarms 82 in the slots 80 comprises a hand lever 87 mounted upon a rockshaft 88 arranged in the base of the side support 29 (Figs. 6, 7 and 9).The shaft 88 extends in toward the platform, and an arm 89 is fixed uponthis shaft at its inner end. This arm is connected by a bent link 91 toa vertically reciprocating lock bar 92 slidably mounted in brackets 93and 94 fixed to the presented face of the side support 29.

An angle iron 100 is fixed to the platform just above the lever arms 82at the control side of the apparatus, and this angle iron is providedwith a slot through which the bar 92 is moved downwardly to withdraw thepins 73 from car holding position. The bar 92 is normally arranged inthis slot to depress the arms 82 into the slots 80 locking the platformin car receiving position.

An arm 96 is fixed upon the shaft 88 and is connected with a rod 97which is arrangedthrough the opposite side of the side support 29 andembraced by a spring 98 to cause the lever 87, the shaft 88, the link91, and thebar or plate 92 to move down into pin releasing position andinto position to lock the platform against movement.

The lever 87 is loosely mounted upon the shaft 88 and upon this shaftthere is also provided a collar 121 fixed to the shaft and having anoutwardly extending arm 122 which is provided with a pin 123 at itsouter end arranged in the path of travel of hand lever 8'7. A quadrant98 is arranged alongside the lever 87 and this quadrant is provided withthree notches indicated by reference characters 99--99-99".

The lever 87 has four positions, the first of which is at the limit ofthe movement toward the right (viewing Fig. 6) and when a notch engagingpin 101 carried by the lever is to the right of all of the notches. Thusarranged the bar92 is in its lowermost position with the arms 82 pressedwell down through the slots 80 of the angle irons 90 and the pins 73vout of locking engagement with the car. As the car approaches centralposition it is intended that the lever 87 shall be moved to engage itspin 101 with the notch 99 i. e. the lever is moved to the secondosition. Thus arranged the bar 92 has been lifted sufiiciently to permitthe pins 73 to bear against the channels .72 of the car and to snap intothe slots '15 when the car arrives at the center of the platform.

At this stage in the operation the arms 82 earlier mentioned are stillarranged in the slots 80. The car is thus locked upon the platform andthe platform is locked in the support. The lever 87 is then moved toengage its pin in the notch 99 of the quadrant and'in this movement thebar 92 is raised sufiiciently to permit the spring to lift the arms 82out of the notches so that the platform is unlocked.

. Means, however, are provided for preventing dumping movement of theplatform until the lever 87 has been given further movement t6 permitengagement of the pin 101 in the slot 99. This means comprises one ormore vertically arranged upwardly extending arms 105 (Fig. 1) fixed upona shaft 106 rotatably supported upon a cross frame member 107 in thepit. The arms 105 when in normal position are arranged just beneath theplatform at the incoming side. An arm 108 is also fixed upon this shaftat the control side of the apparatus and a link 109, connected with theupper end of the arm 108, extends beneath the control into engagementwith one arm of a bell crank lever 110 suitably pivoted at 111. A spring112 pulls or tends to pull the arm or arms 105 into the upright normalposition shown in Fig. 1, and into suitable engagement with a fixed stop105'.

The other arm of the bell crank lever 110 has a pin 124 arranged in aslot 125 in the lower end of a union link 126 which extends down from apivotal connection 127 with an arm' 128 on shaft 88, the parts being soarranged that the link. 126 is arranged close against the sidewall ofthe pit out of the path of travel of the angle iron and lever arm 82.

When the lever 87 is moved into engagement with the notch 99, i. e.,into its farthest position toward the left (viewing Fig. 6) the arm 128is moved downwardly sufiiciently to cause the pin 124 to be engaged bythe upper end of the slot and the bell crank lever swing to move the rod109 to push the arms 105 out of platform supporting position. The slotin the link 126 is of sufficient length to permit the earlier describedmovements of the lever 87 without effect upon the position of the arms105, these being held beneath the platform by the spring 112. When a caris to be dumped the bar 92 is moved up by the control to arrange itslower end above the angle iron 100, whereupon as other parts arereleased by the control the platform withits loaded car swings to aninverted position where it is held by the brake during dumping. Afterdumping release of the brake causes the platform to return with theempty car by gravity back to normal position. The angle iron 100, whichis fixed to'move with the platform, is a straight member having its endsbeveled. as may be seen in dotted lines in Fig. 6. As the platform withits car returns to normal position the angle iron acts as a cam toinsure that the bar 92 is maintained in an elevated release positionunitl the platform has arrived at or substantially at its central carre-- ceiving position.

In inverting, the platform swings in a clockwise direction (viewingFig. 1) through the slightly overbalancing effect of two vibrators 102which are mounted in the platform beneath and near the righthand end ofthe car and in position to engage the presented portions of the carchassis to vibrate the car. As shown in Fig. 5, each vibrator comprisesa cylinder 103 adapted to actuate a pin or plunger 104 to engage thechannels '72 and shake them with sufficient violence to cause all or.substantially all of the material in the inverted car to be discharged.As the car reaches inverted or dumping position the brakes are tightenedby release of the foot lever, and the vibrators operated. The car isreturned to normal position by gravity and by merely releasing thebrakes. The overbalancing eifect of the vibrators insures that return tonormal car receiving position is in counter-clockwise direction.

Before releasing the brakes by operation of the foot lever, the operatormoves lever 8'7 to position #3. The platform in returning passesslightly its horizontal position swinging the supports to the right(viewing Fig. 1) against the action of the spring 112. As soon as theplatform passes these stops or supports they snap back into sup-,

porting position under the platform. Under the control of the operatorusing the lever the platform is then permitted to settle gently uponsupports 105. Lever 87 is then moved to position #1 where the platformis locked and the car released.

In the return movement, if the operator releases unnecessarily severeshocks upon the locking mechanism.

Means are provided to prevent manipulation of the control as a car ismoving onto or off of the platform. A supplemental .arm Wis providedupon each end of each shaft 78 and at each side at each end of theplatform. A'pin 73 similar to the pin 73 and similarly mounted, isarranged at the upper end of each arm 77. .Each of these pins, however,unlike the pins 73 is provided with a car engaging end too large toenter into a presented opening 75 in the chassis .channels. effort ismade to operate the controls to look a car in place before thepreviously emptied car has entirely cleared the platform, the lefthandpins 73 (viewing Fig. 4) will engage the channel 'of the lifting car andprevent movement of the pins 73 into locking position and'release of thearms '12 until the channels of the departing car have moved beyond thepins 73*. Likewise if ef fort is made to operate the control while a carmoving onto or is projecting over the platform, the pins??? at the right(Fig. 4) will engage the forward ends of the chassis channels andoperation of the control is prevented.

The pins 73% also give Wider latitude of. control to the operator. Assoon as acar is well started onto the platform the lever 87 may be movedinto the notch 99 so that the adjacent pins 73 .bear against the forwardend of the chassis channels. Because of the large size of the ends ofthese pins they cannot en er the openings '75 as they are presented sothat the car moves on until the pins 73 are in position to snap intothese openings, i. e. until it arrives at the center of the platform.

I have provided means for inverting the tipple by hand, and in theabsence of a loaded car should repair or other condition renderinversion desirable. the idle trunnion 38 and this worm wheel carriesone part 114 of a jaw clutch. The other part .115

is splined on the end on the trunnion. The worm wheel is adapted to berotated to rotate the platform by worm 116, in turn adapted for rotationby a cranl; 117.

A worm wheel 113 is loosely mounted on- It is thought that the inventionand many of its attendant advantages will be understood from theforegoing description, and it will be apparent that various changes maybe made in the form,

construction and arrangement of the parts without departing from thespirit and scope of the invention or sacrificing all of its materialadvantages, the form hereinbefore described being merely a preferredembodiment thereof.
